*If q is a multiple of prime numbers, is q a multiple of r?*

*1) r is less than 4*

*2) q = 18*

*Answer: E*

*From Statement (1) -- q can be positive and r can be negative.*

*r can also be a real number but not necessarily an integer.*

*Hence insufficient.*

*From Statement (2) -- q = 18.*

*But r can be negative or can be positive.*

*r can also be a real number not an integer*

*Hence insufficient*

*Taking both statements (1) and (2) together -- Again r can be positive or negative.*

*And again r can also be a real number.*

*Hence insufficient*
